摘要
为评价、筛选综合性能佳的低温相变储热材料,将层析分析法和多准则妥协解排序法引入相变材料多属性决策领域,构建了三层次六属性的低温相变材料评价体系,建立了基于层次分析法和多准则妥协解排序法的优选模型,指出了评价的方法和步骤。在此基础上,利用建立的模型对10种相变材料进行了综合性能优选排序。研究结果表明:层次分析法和多准则妥协解排序法在相变储热材料的筛选上具有可行性和统一性,所选出综合性能最佳的无机相变材料为三水合乙酸钠,有机相变材料有硬脂酸和石蜡。
In order to evaluate and filter the best low-temperature phase change materials for thermal energy storage, Analytic hierarchy process（AHP） and VlseKriterijumska Optimizacija I Kompromisno Resenjein Serbian （VIKOR） were introduced in the field of phase change material selection. The evaluation system of three levels and six different attributes was constructed and the optimization model based on AHP and VIKOR was established. Meanwhile, the evaluation method and steps were pointed out. Based on this, by the use of established model, ten kinds of low-temperature phase change materials were sorted according to their comprehensive performance. The results show that the established evaluation system and model based on AHP and VIKOR is effective and practical for selecting optimal PCMs. Sodiumacetate trihydrate and stearic acid are found to be the optimal inorganic and organic phase change materials, respectively.
